“Donald Trump’s inflammatory rhetoric has crossed the line from spreading hatred to inciting violence,” Nihad Awad, the national executive director for the Council on American-Islamic Relations, said in a statement.

“By directly stating that the only way to stop terrorism is to murder Muslims in graphic and religiously-offensive ways, he places the millions of innocent, law-abiding citizens in the American Muslim community at risk from rogue vigilantes,” the statement continued.

The Republican presidential candidate told supporters at a rally in Charleston, S.C., on Friday about US General John Pershing executing Muslim prisoners in the Phillipines the early 20th century.

“He took 50 bullets and he dipped them in pig’s blood,” Trump said. “And he had his men load his rifles and he lined up the 50 people, and they shot 49 of those people. And the 50th person, he said, ‘You go back to your people and you tell them what happened.’ And for 25 years there wasn’t a problem."
